#     RECIPE Example #4: Regression model with data from several
#                        batches
#
#  -- In this example, we have 72 strength observations on data
#     from 8 batches.  A straight-line regression is fit with
#     two fixed levels (temperatures).  B-basis values are calculated
#     for 7 points along this curve.
#
#  -- ntot, nlvl, nbch, npar, npts, prob, conf
 72 2 8 2 7 .9d0 .95d0
#
#  -- There are two fixed levels, corresponding to
#     75 and -67 degrees.

 1 -67
#
#  -- The following 72  rows give the fixed level in the
#     first column, the batch in the second column, and the
#     strength observation in the third column.
